That's right. The green lights don't appear until you sign in (makes sense... the system doesn't know who you are or when you last visited until you sign in, which activates cookies).

But there should be a way for you to request your password be sent to your email, if you can't recall it. Alex is right that you shouldn't have to create a new profile just because you forgot your password. I'm sure they'll straighten it out for you and you can go back to your original profile and username. :-D
